To all whom it may concern:
' Be it known that 1, Jason Emu. Noneennarn, a citizen of the United States, residing at The Hague, Netherlands, have invented certain new and useful Improvements in Means for Damming Up Semisolid Substances, of which the following is a specification.
My invention refers to a methodof umping or damming P up semi-solid bodies by means of viscoslt pumps and more especially pumps wor ing with helical grooves.
Liquid and semi-solid bodies show a different action in viscosity pumps. As an example the viscosity threads deserve mentioning, which seal a chamber standing under pressure against another chamber. This pressure shall be. called hereafter packing:
pressure. This is done for means of 'aviscosit the liquid contained in the pressure chamber, or else a packing pressure is generated by means of a viscosity thread and a viscous liquid, especially oil, which pressure is higher than the pressure to be sealed 0d and is" destined to prevent the viscous liquid held under packing pressure from leaking out by means of a counter thread, which is able to generate. a pressure corresponding no to the packing or dammin'g-up ressure.
With viscous li uids it is s cient that ,the counter; threa be'con structed for the same pressure as the main thread; but if semi-solid bodies are used-such as grease 5 and the like-the grease oozes out on the side of the cbunter thread averted from the P ed for t e same pressure as the-main thread. The reason for this is given in the eculi; w arity of the semi-solid bodies that o y then the viscosit acts fully, when a close contact is esta lished between the individual particles and with the walls between which the viscosity action is to take place.- This pressure is called the .adhesion and cohesion pressure. lit this is not the case, as in the counter thread for oils previously mentioned, parts of the ease are pressed through the thread by t e pressure without 535) any suficient adhesion taking place on the walls or within the grease itself, and not instance b thread pressing bac if the oounterthread is constructsuficiently close contact takes place between the articles and the wall. Tile thread really forms a viscosity pump. lln contradistinction to centrifugal pumps, for instance, to screw pumps, to gear wheel pumps, to turbine pumps and so forth, the
action of the viscosity pumps depends on making use of the viscosity, the cohesion of the particles of the liquid and their adhesion tothe walls to create pressure and to counter threads the generation of the ad-. hesion pressure is done by applying more" thread than would be necessary to generate a pressure equal to that generated by the main thread, if the viscosity were in full action. Thus the counter thread is calculated for a higher pressure than the main (Bil thread. The necessary adhesion pressure may also he by centrifuga action; likewisethe adhesion pressure can be generated, e. g. by means of a wiper. In the case of a counter or insulation thread for the generation of the adhesion pressure a resistance may be inserted in the way of the grease, which moves in the insulation thread against its pumping tion. This resistance may be any throtstricted to the constructions previously described in detail, butit. comprises as well enerated in other ways, e. g.,'
'00 iding or packing. The invention is not re-- The shaft a rests in the bearing a,- the lubrication ot this hearing is done by grease stored in the receptacle f. The viscosity thread :2 leads the grease with pressure to V e on the other side of the supporting face which is able to enerate a higher pressure than that preva' ing in the grease which wets the supporting face l Finally the oozing out of the grease on the side, where the admission of the grease takes place, is prevented by a third thread 8 The new appliance is especially suitable for a bushin for the revolving part. By one of twot eads grease is pressed along, which, bein kept back by the counter thread, is he d at avery high pressure and thus sealed the ressure chamber filled with aliquidorthe'e I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will skilled in the art.
I claim A device for placing viscous sub under pressure comprising in combination, members in contact with one another, one being adapted to revolve relatively to the other, a s iral groove in the contact surface of one 0 said members, means for feeding a viscous substance mto the suction end of of sai first groove. In testimony whereof I aflix my signature.
